Description
Technical field：
The present invention relates to organosilicon material technical field, and in particular to a kind of suppression coating pigment reunite and sedimentation organic
Silicon additive.
Background technology：
Pigment is the coloring material of coating, in order to give paint colors, so as to strengthen aesthetic property.But in coating process
Middle discovery, it sometimes appear that agglomeration after adding a pigment in coating, even if strengthen stirring to be also difficult to make pigment uniformly mix
Close；In addition during coating stores, also occur that homodisperse pigment particles are deposited to coating bottom, so as to affect to apply
The normal use of material and coloring effect.For this situation, our company develop a kind of suppression coating pigment reunite and sedimentation
Silicone additives, promote the dispersed of pigment, so as to ensureing coloring effect and mitigating the work increased due to compo
Amount.
Content of the invention：
The technical problem to be solved is to provide a kind of suppression that ensure that coloring effect and mitigate workload
The silicone additives that coating pigment processed is reunited and settled.
The technical problem to be solved is realized using following technical scheme：
The silicone additives that a kind of suppression coating pigment is reunited and settled, are made up of the raw material of following parts by weight：
Silicone emulsion 10-15 part, polyvinyl butyral resin 6-11 part, Modified Chlorinated Paraffin 4-8 part, C5 Petropols 3-6
Part, activated magnesia 2-4 part, three Phosphoric acid monohexadecyl ester 2-4 parts, microwax 1-2 part, sulfated castor oil 1-2 part, sulfurized lard
1-2 part, 2- methyl-cyclopentanone 1-2 part, dimethylphosphite 1-2 part, zinc dihydrogen phosphate 0.5-1 part, ethylenediamine tetra-acetic acid 0.5-1
Part, cyclopropyl magnesium bromide 0.5-1 part, sodium tripolyphosphate 0.5-1 part.
Its preparation method comprises the steps：
(1) polyvinyl butyral resin and C5 Petropols are added in silicone emulsion, adding with 10-15 DEG C/min under stirring
Thermal velocity is warming up to 110-120 DEG C of isothermal holding 10min, adds microwax and sulfurized lard, continues to be incubated at such a temperature
5min is processed, obtains final product material I；
(2) sulfated castor oil and 2- methyl-cyclopentanone are added in Modified Chlorinated Paraffin, is sufficiently mixed after 0-5 DEG C of ring
Sealing and standing 5h in border, is subsequently adding three Phosphoric acid monohexadecyl esters, dimethylphosphite and zinc dihydrogen phosphate, and under agitation with
The firing rate of 15-20 DEG C/min is warming up to 90-100 DEG C of insulation mixing 10min, obtains final product material II；
(3) activated magnesia, ethylenediamine tetra-acetic acid and cyclopropyl magnesium bromide are added in material I, and under agitation with 10-
The firing rate of 15 DEG C/min is warming up to 110-120 DEG C of isothermal holding 10min, then with 15-20 DEG C/min's under ice salt bath
Cooling velocity is cooled to 0-5 DEG C of isothermal holding 10min, is eventually adding material II and sodium tripolyphosphate, is sufficiently mixed uniform.
The preparation method of the Modified Chlorinated Paraffin is：0.5-1 part expanded graphite powder is added in 15-20 part chlorinated paraffin
With 0.5-1 part potassium citrate, stirring makes which be uniformly dispersed, and proceeds to rotating speed 10-15r/min grinding in ball grinder 1h, adds
3-5 part pentalyn, 2-3 part polyethylene glycol oxide and 1-2 part 1-METHYLPYRROLIDONE, using plasma after being sufficiently mixed
Surface treating machine processes 10s to gained mixture, is then cooled with the speed of 10 DEG C/min under ice-water bath, treats that temperature drops
The insulation standing 2h to after 0-5 DEG C, reuses Surface Treatment with Plasma machine and processes 10s, finally naturally cool to room temperature.
Chlorinated paraffin strengthens its compatibility with other raw materials through above-mentioned modification, promotes the uniform mixing of raw material；
While dispersion force and the electrostatic force between pigment particles can be reduced, so as to promote the dispersed of pigment particles.
Using front through pretreatment, its processing method is the activated magnesia：First 10-15 part activated magnesia is added
Etc. in weight water, 30min after being uniformly dispersed, is stood, 2-3 part polyacrylamide and 0.5-1 part silane coupler is added, fully
15s is processed using Surface Treatment with Plasma machine after mixing, 0.5-1 part ferrocene and 0.5-1 part glass powder is subsequently adding, is filled again
3min is processed using microwave reactor after point mixing, gained mixture sends into freeze drier, pulverize after fully dry
End.
The operating frequency of the Surface Treatment with Plasma machine is 40Hz, power is 600W.
The operating frequency of the microwave reactor is 2450MHz, power is 700W.
Activated magnesia is not only significantly improved its adsorptivity, makes pigment equal by adsorption pigment particle through pretreatment
Even dispersion；Can also pass through to increase the molecular structure of activated magnesia itself, to strengthen the space resistance between pigment particles, so as to
Reduce the reunion of pigment particles.
The invention has the beneficial effects as follows：
(1) with silicone emulsion as primary raw material, it is aided with polyvinyl butyral resin, Modified Chlorinated Paraffin and multiple auxiliary agents and is obtained
The silicone additives for suppressing coating pigment to reunite and settle, short preparation period and low cost is applied to, and in preparation process
By way of strict control rises gentle cooling rate and charging sequence, each raw material is made to act synergistically to promote the equal of pigment
Even dispersion；
(2) made silicone additives are on the one hand by reducing dispersion force and electrostatic force and increase between pigment particles
Space resistance is preventing pigment agglomerates；On the other hand promoted by the suction-operated of raw material in silicone additives and compatibility
Pigment dispersed, prevent pigment agglomerates and sedimentation further；
(2) add in coating after mixing made silicone additives with pigment, pigment low whipping speed 250- can be made
Mix with coating composition in 5s under 500r/min, naked eyes occur nothing pigment agglomerates phenomenon, and determined by instrument detection
Pigment has been dispersed in coating composition；While made colored paint was stored up according to 12 months shelf-lifves of national regulation
Put, do not occur pigment sedimentation phenomenon after testing, and made coating is not directly had difference using its coloring effect rear.
